"This passage makes it clear that God may, if he so chooses, visit disaster upon us but that not every disaster is God's explicit doing."

I don't see that passage as making your coclusion clear at all. All this passage says is that when God visits disaster on someone it doesn't mean it was because they were worse sinners than those who weren't victims of such a disaster. Judgment will come to all. As Amos tell us, all disasters are the work of God, we just have no business trying to assume we know God's reasons or motives for each act he does.
